is there a site/magazine/resource that will be able to let me know all I need
to know about medical tourism in Asia?

I need to know the hospitals avaliable, which hospitals are good at
which types of operations, etc.

If there is no standalone resource, please do provide places which
gives me as much information as possible.

Hello meow1981-ga,
Medical tourism is catching in a big way in India. The hospitals are
modern, healthcare is excellent and very cheap compared to US &
Europe.

Hospitals list in India can be accessed at 

 www.helplinedatabase.com/hospitals-india/

Any specific information requred for hospitals in Hyderabad or
Bangalore, I can provide if you let me know the type of operations you
are interested in.
